1 - 39 ADJUSTMENT
1.5.1 Adjustment of paper aligning value
If necessary, you can extend the feed roller life slightly by increasing the paper aligning value as a temporary
measure.
<Procedure> (Use code 450~458 in the test mode “05”.)
(1)
(2) Check the copy for image void and if there is
any, reduce the new value to “31”
→
“30”
→
“29”… until no void occurs. Check for paper
misfeeding.
When the aligning value is increased, noise
caused by the paper scraping against the mylar
may possibly be increased.
(3) The same procedure can be used for the
Duplexer, LCF and manual feed.
Note: When frequent paper jams occur near the aligning roller caused by using special thin paper other
than that specified, the aligning value can be changed (reduced) as a measure. However, when
the aligning value is reduced excessively, this may cause the deviation of leading edge registra-
tion. Therefore, make sure that no deviation occurs while adjusting the value.
